I have a requirement for a switch that works down to a 10kHz. I am looking at the HMC536MS8G or HMC536LP2 but there is no typical and power de-rated data or graphs for IL, IP3, P1dB, max RF input to show the performance between 9kHz and 1MHz.
The reason I ask is that power de-rating of IP3, P1DB, and max RF input can be very significant for RF switches between 10kHz and 1MHz (typically on the order of -20 to -25 dB less than specs given for frequencies above 10MHz) and I would need to know this information before selecting the HMC536 part. I would like to use this Analog Devices but without this information I would need to select a competitor's part since their datasheet provides graphs of IP3, P1DB and max RF which I need. If you can provide data that would be very helpful.
Our max input power is +10dBm but we are prepared to de-rate this a bit at very low frequencies (below 1MHz). From what I've seen, after looking at comparable RF switches, the max RF input is between +9dBm to +15dBm depending on temperature and supply voltage. That would be acceptable. similarly I'm prepared for lower P1dB, P0.1dB and IIP3 but I would need the data and graphs so I can prepare our spec based on the selected RF switch spec.
I'm also looking at the HMC1119 which has data/graphs down to very low frequency and may opt for that switch, however, one of the benefits of the HMC536 is positive control, therefore, there is no need for an additional negative supply and conversion logic.
